A DEADLY plague could sweep across Europe, doctors fear, after an outbreak of a virus in Ukraine plunged the country and its neighbours into a state of panic.

A cocktail of three flu viruses are reported to have mutated into a single pneumonic plague, which it is believed may be far more dangerous than swine flu. The death toll has reached 189 and more than 1 million people have been infected, most of them in the nine regions of Western Ukraine.

President of Ukraine Viktor Yushchenko has called in the World Health Organisation and a team of nine specialists are carrying out tests in Kiev and Lviv to identify the virus. Samples have been sent to London for analysis.

resident Yushchenko said: “People are dying. The epidemic is killing doctors. This is absolutely inconceivable in the 21st Century.”

In a TV interview, the President added: “Unlike similar epidemics in other countries, three causes of serious viral infections came together simultaneously in Ukraine – two seasonal flus and the Californian flu

“Virologists conclude that this combination of infections may produce an even more aggressive new virus as a result of mutation.”

Prime Minister Yulia Tymoshenko has been touring hospitals where victims are being treated and presidential elections in January could be cancelled .

Four men and one woman have died from the flu in Lviv, said emergency hospital chief doctor Myron Borysevych. Two of the dead patients were in the 22-35 age group, with two others over 60. He diagnosed the disease as viral pneumonia.

“We have sent the analyses to Kiev. We don’t believe it’s H1N1 swine flu. Neither do we know what kind of pneumonia it is.”

Universities, schools and kindergartens have been closed, public meetings have been banned and theatres shut. Last week several border crossings in the country were also closed.

Last night reports emerged of profiteering over face masks, which have sold out since the outbreak. There are also incidents of anti-virus medication being sold for exorbitant prices. A spokesman for the World Health Organisation said: “We do not have a time scale for the results of the tests in London, although some preliminary results have been obtained. I cannot tell you what they are.

“We did not have enough of the virus samples so we will have to grow some more before we can come to a conclusive decision about its nature.”

Neighbouring Poland has called on the EU to take action, fearing the mystery virus may spread westwards.

Prime Minister Donald Tusk has written to European Commission President Jose Manuel Barroso and the Swedish Prime Minister, Fredrik Reinfeldt, who holds the EU presidency, saying: “The character of this threat demands that rapid action be undertaken at the European Union level.”
